TO- ALL WHOM IIT MAY CONCERN:

Be it known that I, CHARLES WEBSTER, of New Haven, in the county ofAddison, and State of Vermont, have invented a new and usefulImprovement inHeating Feed-Water for Steam-Generators; and I do herebydeclare that the following is a full, clear, andexact description ofthesame, .reference 'being had to the annexed drawings, making part of thisspecification, in which- Fgure'l -is a plan,l and Figure 2 is a verticallongitudinal section.

Thev same letters indicate the same parts in both figures.

,` In the annexed drawings, A is .the fire-box ol' a ste'nm-generator,,and- B atonk for containing the feedwater. l C C arehorizontal metallic pipes, placed in the tank, the ilona of waterthrough saidvppes' being regulated by the valve D at will. These pipesare connected with4 the pipes'F F by elastic sections of pipes E E,which may be ofvIndia rubber or other suitable material. The 'pipes F Fare attached near the ends of the heater G, which is a cast-iron retort,inserted in the tire-box. Colla rs, FL, are attached the pipes Fhyset-screws, which are connected by rods to the crank H,operatedby-the` lever H. l Asthis levier. is'moved, the retort Gr will be forcedinto or AWithdrawn from the lire, entering between the wings A', whichproject from each side of the lire-box, above and below the retort, andthus place the cle'greeof bent -to which the water in theretort` shallbe subjected, entirely within the control of the engineer. y lhe wnter,when it has filled the retort,

lwill. be heated, and the Aforce of the -stento generated therein willexpel the heated water, and permit colder'v Water to loiv in frein thetank, thus maintaining a free circulation, through the tank', pipes, andheater,

`What I claim as my invention, and desire to secure by Letters Eatent,is- An apparatus for heatingthe feed-water of asteam-generator,lcombining the following elements, viz, a tank B, and asystem 'of pipes, connecting it with a heater, G, so arranged that thelatter may beladjusted in itsposition inthe fire-box, substantiallyasset forth. i p

" In testimony whereof, I have signed my name to this specicatien in thepresence'of two subscribing witnesses.
